The colored barrel of this pen is translucent, allowing you to see your ink level. The cap design permits a multi-layered view inside the design. The pen features an solid color resin finial and piston knob, a silver clip, and a silver stainless steel #6 nib. It also comes with a glass eyedropper to fill the pen with your favorite ink. An ebonite piston and rubber gasket seals the feed off from the barrel when fully depressed, reducing the risk of leakage and burping. By unscrewing the blind cap and loosening the rod at the rear of the barrel, you open up the ink flow to the feed. During long writing sessions, leave the shut-off valve open to take advantage of the impressive ink capacity.\u003c\/p\u003e Opus 88 OMAR Fountain Pen Specifications\u003cul\u003e\n\u003cli\u003e Pen Material: Translucent and opaque resins.\u003c\/li\u003e \u003cli\u003eNib: Stainless steel #6 nib with plastic feed\u003c\/li\u003e \u003cli\u003eFilling System: Eyedropper (includes glass eyedropper) with shut-off valve to safeguard against leakage.\u003c\/li\u003e \u003cli\u003ePen Length Closed: 5.89 in. \/ 149.5mm\u003c\/li\u003e \u003cli\u003ePen Length Open (Cap Off): 5.33 in. \/ 135.5mm\u003c\/li\u003e \u003cli\u003ePen Length Open (Cap Posted): 7.11 in. \/ 180.5mm\u003c\/li\u003e \u003cli\u003ePen Body Max Diameter: 0.55 in. \/ 14mm\u003c\/li\u003e \u003cli\u003ePen Grip Section Diameter: 0.43 in. \/ 11mm\u003c\/li\u003e \u003cli\u003ePen Total Weight: 1.19 oz \/ 34g\u003c\/li\u003e \u003cli\u003eInk Capacity: ~3.5ml\u003c\/li\u003e \u003cli\u003eGift boxed with instruction booklet\u003c\/li\u003e \u003cli\u003eMade in Taiwan\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Opus 88 Pens","offers":[{"title":"Medium","offer_id":33818704117899,"sku":"96087706M","price":123.0,"currency_code":"USD","in_stock":false},{"title":"Fine","offer_id":33818704150667,"sku":"96087706F","price":123.0,"currency_code":"USD","in_stock":false},{"title":"Extra Fine","offer_id":33818704183435,"sku":"96087706EF","price":123.0,"currency_code":"USD","in_stock":false},{"title":"Broad","offer_id":33818704216203,"sku":"96087706B","price":123.0,"currency_code":"USD","in_stock":false},{"title":"1.5mm Stub","offer_id":33818704248971,"sku":"960877061.5","price":123.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1693\/8459\/products\/opus-88-omar-fountain-pen-in-baby-blue-192.jpg?v=1762201408"},{"product_id":"opus-88-koloro-fountain-pen-in-color-demo","title":"Opus 88 Demonstrator Fountain Pen in Color","description":"\u003cmeta charset=\"utf-8\"\u003e\u003cmeta charset=\"utf-8\"\u003e\n\u003cp\u003eFor true purists of the writing experience, Opus 88 crafted the DEMO with translucent acrylic resin.
